Description

Technical Field

[0001] The present application relates to the technical field of power equipment detection, and in particular to an intelligent inspection system for power equipment. Background Art

[0002] With the rapid development of society and the continuous prosperity of the economy, people are increasingly dependent on electricity in all areas of production and life, and their demand is showing a significant upward trend. Against this background, my country's power engineering construction industry has ushered in an unprecedented opportunity for vigorous development, and the scale of construction has continued to expand. From the construction and upgrading of large-scale power stations to the extension and optimization of power transmission networks throughout urban and rural areas, the power infrastructure is gradually building a larger and more complex system. Today, electricity has been deeply integrated into every corner of people's lives and has become an indispensable key element in maintaining the normal operation of modern society. Whether it is lighting and electrical appliances in daily family life, or various mechanical operations and automation processes in industrial production, or even the operation of various facilities in the commercial service field, they are inseparable from the stable supply of electricity.

[0003] Therefore, in the entire process of power system operation, the detection of power equipment occupies a pivotal position. First of all, the voltage and current parameters of power equipment are like the "barometer" of its operating status. Whether the voltage is stable within the rated range, the size and fluctuation of the current, all directly reflect whether the equipment is in normal working conditions during operation. Stable and appropriate voltage is the basis for ensuring the normal operation of electronic components, electromagnetic devices, etc. inside power equipment, and abnormal changes in current often indicate that the equipment may have problems such as overload, short circuit, leakage or internal circuit failure. For example, excessive current may cause severe heating of the equipment, thereby damaging the insulating material and causing serious consequences such as electrical fires; while too low current may cause the equipment to fail to start normally or operate inefficiently, affecting the output power and power supply quality of the entire power system.

[0004] Secondly, the surrounding environment of power equipment also has a profound and significant impact on its operation. Environmental factors such as temperature, humidity, dust, and electromagnetic interference are constantly testing the stability and reliability of power equipment. Excessive temperature may overload the cooling system of the equipment, causing internal components to overheat and age, shortening the service life of the equipment, and even causing sudden failures; excessive humidity may cause rust and corrosion of metal parts inside the equipment, affecting the reliability of electrical connections; the accumulation of a large amount of dust will hinder the heat dissipation channel of the equipment, and may also cause electrostatic discharge, interfering with the normal operation of the equipment; and strong electromagnetic interference may damage the control signal and communication line of the equipment, causing equipment malfunction or data transmission errors.

[0005] Therefore, in order to ensure the safe, stable and efficient operation of power equipment, it is particularly important to build a complete and reliable real-time detection system to accurately and continuously detect the various operating parameters and environmental parameters of power equipment. This not only helps to timely discover potential operating hazards of equipment, take effective preventive measures in advance, nip faults in the bud, avoid large-scale power outages caused by equipment failures, and ensure the continuity and stability of power supply, but also can provide detailed and accurate data support for the optimization and upgrading of power systems, the formulation of maintenance plans, and the rational allocation of resources, and promote the entire power industry to develop in a more intelligent, efficient, and sustainable direction. Summary of the invention

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] The present application provides an intelligent inspection system for electric power equipment, which includes an intelligent online inspection technology module, which is used to realize operating status monitoring and environmental monitoring of electric power equipment, and has automatic inspection, automatic early warning and automatic report output functions.

[0008] Through the intelligent online inspection technology module, all-round automated monitoring and management of power equipment operation is realized. The automatic inspection function can perform regular or on-demand inspections on equipment according to preset procedures and paths without continuous human intervention, greatly improving inspection efficiency and reducing manual inspection costs; the automatic early warning function can issue an alarm in time when equipment operating parameters deviate from the normal range or abnormal environmental conditions occur, allowing operation and maintenance personnel to respond quickly to avoid further deterioration of faults; the automatic output report function helps to organize and analyze inspection data, providing data basis for the formulation of long-term maintenance strategies, performance evaluation and overall planning of power systems, and realizing scientific and standardized operation and maintenance of power equipment.

[0009] Specifically, it includes a comprehensive inspection and prediction unit, which is used to perform comprehensive inspection and prediction between multiple device units such as indicator lights, switches and meters, so as to realize unmanned and real-time monitoring of various equipment and environmental indicators.

[0010] The existence of the comprehensive inspection and prediction unit makes the inspection of each key device unit of the power equipment (such as indicator lights reflecting the working status of the equipment, switches controlling the on and off of the circuit, meters displaying operating parameters, etc.) more systematic and comprehensive. It can conduct collaborative inspections on a variety of different types of devices under the same system framework, improving the comprehensiveness and accuracy of the inspection. At the same time, the unattended real-time monitoring based on this comprehensive inspection not only reduces manpower input, but also monitors the equipment and environment 24 hours a day, ensuring that the power equipment is always in a state of attention, and any subtle abnormal changes are captured in time, effectively improving the reliability and stability of the operation of the power equipment, and ensuring the continuity of the power supply.

[0011] Specifically, a linkage alarm module is provided, which can simultaneously link with multiple configured sensors to timely identify, record and automatically and quickly alarm when there are emergency accidents such as abnormal increase in environment and equipment temperature, abnormal sounds on site, illegal intrusion into the area, fire, smoke and water leakage.

[0012] The linkage alarm module plays a key role in the face of various emergency situations. By working in collaboration with various configured sensors, it can quickly and accurately identify the occurrence of abnormal situations. For example, an abnormal increase in ambient temperature may indicate a heat dissipation failure or fire hazard in the equipment, an abnormal sound may indicate a mechanical failure or discharge phenomenon inside the equipment, and an illegal intrusion into the area may threaten the safety of power facilities. Timely identification ensures that abnormal situations will not be missed. The recording function provides detailed original data for subsequent fault analysis, and the automatic rapid alarm can notify the operation and maintenance personnel or relevant security departments at the first time, so that they can quickly take measures, such as emergency repairs, launching emergency plans, etc., to minimize the damage caused by accidents to power equipment and the impact on power supply, ensure the safety and stability of the power system, and also protect the physical safety of power facilities.

[0013] Specifically, it has the function of infrared detection of equipment, and uses an infrared thermal imager to detect the temperature of power equipment to analyze the operating status of the equipment.

[0014] The infrared detection function of the equipment can obtain the temperature distribution information on the surface of the power equipment in a non-contact manner with the help of an infrared thermal imager. Since the temperature characteristics of power equipment in normal operation and fault state are significantly different, by performing infrared detection on the equipment, overheated parts of the equipment can be discovered in time, such as overheating caused by increased contact resistance due to loose connection points, and overall temperature rise caused by overload operation. This detection method does not affect the normal operation of the equipment, and can detect potential thermal fault hazards in advance, prevent serious accidents such as equipment damage, short circuits, and even fires caused by overheating, improve the reliability and safety of power equipment, and also help optimize the equipment's operation and maintenance plan, extend the equipment's service life, and reduce operation and maintenance costs through targeted maintenance and adjustments.

[0015] Specifically, an ultrasonic partial discharge detection function is provided, which uses ultrasonic sensors to detect partial discharge conditions of power equipment and evaluate the internal insulation status of the equipment.

[0016] The ultrasonic partial discharge detection function uses ultrasonic sensors to detect ultrasonic signals generated by partial discharge inside power equipment. Partial discharge is an important early indication of insulation degradation in power equipment. When partial discharge occurs inside the insulation, ultrasonic signals are generated. By detecting this signal, the insulation degradation can be discovered before it is completely broken down, and the insulation status can be evaluated. This enables operation and maintenance personnel to take measures in advance, such as replacing insulation components and adjusting operating parameters, to effectively prevent major accidents such as equipment short circuits and power outages caused by insulation breakdown, improve the insulation reliability of power equipment, and ensure the stable operation of the power system. In addition, since problems can be discovered at an early stage, large-scale repair and replacement costs after equipment failure can be avoided, which has significant economic and safety benefits.

[0017] Specifically, it includes a switch state recognition module, which uses image recognition or sensor sensing technology to determine the open and closed state of the switch.

[0018] The switch status recognition module uses image recognition or sensor sensing technology to accurately determine the opening and closing state of the switch. In the power system, the correct opening and closing state of the switch is crucial for the on-off control of the power line. Through this module, the status of the switch can be monitored in real time to avoid the switch status errors caused by human misoperation or mechanical failure, such as wrong closing may cause equipment short circuit, wrong opening may cause the expansion of power outage scope and other problems. Timely and accurate grasp of the switch status helps to ensure the normal operation and operational safety of the power system, improve the dispatching flexibility and reliability of the power system, and also provide important status feedback information for the automatic control of the power system, facilitating remote monitoring and intelligent operation.

[0019] Specifically, it has the function of automatic identification of status indicator lights, and uses image processing and analysis algorithms to identify the status information of status indicator lights on power equipment.

[0020] The automatic identification function of the status indicator lights uses image processing and analysis algorithms to identify the status indicator lights on the power equipment. The status indicator lights are intuitive indicators that reflect the operating status of the equipment. For example, the operating indicator light indicates that the equipment is operating normally, and the fault indicator light indicates that the equipment is faulty. By automatically identifying the status of these indicator lights, the operating status of the equipment can be understood remotely and in real time without manual on-site inspection. This not only improves the inspection efficiency and reduces the workload and time cost of manual inspections, but also can promptly detect abnormal status of the equipment, allowing operation and maintenance personnel to respond quickly and take corresponding measures to improve the reliability and maintainability of the operation of power equipment. At the same time, it also helps to realize the intelligent management of power equipment operation and maintenance, and provides basic data support for building smart grids.

[0021] Specifically, it includes a pressure plate position recognition device, which determines the position state of the pressure plate through a high-precision sensor or image recognition means, as well as a circuit breaker state recognition device and a knob switch position recognition device, which are respectively used to recognize the position information of the circuit breaker and the knob switch.

[0022] The pressure plate position identification device, circuit breaker status identification device and knob switch position identification device respectively identify the position status of the pressure plate, circuit breaker and knob switch in the power equipment. Whether the position of the pressure plate is correct or not is related to whether the function of the protection device is normally enabled; the status of the circuit breaker determines the on-off status of the circuit, which has a direct impact on power distribution and equipment safety; the position of the knob switch may also involve different working modes or parameter settings of the equipment. Accurately identifying the position status of these components can ensure the normal operation of the control circuit of the power equipment, prevent equipment failure or protection failure caused by the wrong placement of the pressure plate, the malfunction of the circuit breaker, the wrong position of the knob switch, etc., ensure the safe and stable operation of the power equipment, improve the reliability and operability of the power system, and during the equipment maintenance and commissioning process, the initial status of these key components can be quickly determined to facilitate subsequent operation and maintenance work.

[0023] Specifically, it has the function of reading meter data and uses optical character recognition (OCR) or sensor acquisition technology to read data from various meters of power equipment.

[0024] The meter data reading function uses optical character recognition (OCR) or sensor acquisition technology to read the data of various meters of power equipment, such as voltage, current, power and other parameters. These meter data are important indicators that reflect the operating performance and working status of power equipment. By automatically reading the meter data, real-time monitoring and data collection of equipment operating parameters can be achieved, avoiding errors and delays that may occur in manual meter reading. Based on these accurate and timely data, operation and maintenance personnel can analyze and evaluate the operating status of the equipment, determine whether the equipment is in the normal working range, and promptly discover the performance change trend of the equipment, such as abnormal power increase may indicate equipment overload, voltage fluctuation may indicate grid instability, etc. This helps to formulate a reasonable equipment maintenance plan, prevent equipment failures in advance, optimize the operation and management of power equipment, improve the economy and reliability of the power system, and also provide a data basis for the energy management and dispatch of the power system.

[0025] Specifically, it includes a protection pressure plate position judgment module, which is used to accurately judge the engagement or exit status of the protection pressure plate, and the inspection robot in the system can be flexibly configured with visible light cameras, infrared thermal imagers, partial discharge detection, sound collection, environmental quantity collection and other detection equipment.

[0026] The protection pressure plate position judgment module can accurately judge the input or output status of the protection pressure plate. The protection pressure plate plays a key role in the protection of the power system. Its correct input and output status is related to whether the protection device can act in time when a fault occurs to protect the safety of power equipment and power grid. By accurately judging the position of the protection pressure plate, the reliability and effectiveness of the protection system can be ensured, and the protection failure or malfunction caused by the misoperation or abnormal state of the protection pressure plate can be prevented. At the same time, the inspection robot can be flexibly configured with a variety of detection equipment (visible light camera, infrared thermal imager, partial discharge detection, sound collection, environmental quantity collection, etc.), making the inspection system highly adaptable and versatile. The visible light camera can intuitively capture the appearance of the equipment and the surrounding environment, providing visual information for remote monitoring and fault analysis; infrared thermal imagers and partial discharge detection equipment detect potential equipment faults from thermal and electrical perspectives respectively; sound collection can capture abnormal sounds during equipment operation; environmental quantity collection can monitor environmental parameters such as temperature, humidity, and smoke. The coordinated work of multiple detection devices has comprehensively enhanced the inspection system's ability to detect the operating status and environmental conditions of power equipment, improved the accuracy and comprehensiveness of power equipment fault detection, ensured the safe and stable operation of the power system, and can flexibly configure detection equipment according to different power equipment types and inspection needs, improving the versatility and scalability of the inspection system.
